Filed: 1919-07-22
Abstract: 153,636. Allkin, H. W., and Davies, C. July 22, 1919. Handle-bars.-In handle-bars for motor and other cycles, of the kind embodying in their construction one or more springs adapted to absorb vibration, the springs consist of superimposed strips of steel or other material, one or more of the strips being transversely waved or corrugated between their ends and the other strip or strips being plain. As shown in Fig. 2, such a spring b, consisting of a central plain strip and upper and lower corrugated strips, is used to connect two parts a of the handle-bar, the strips being secured at their ends by screws e to lugs or plugs d. The strips may, however, be brazed, welded, or otherwise secured in solid or, as shown, divided or split plugs. The spring may also be used to control the hinged hand-grip end of a handle-bar.

Abstract: 1288016 Separating and drying coal BIRD MACHINE CO 2 June 1971 [9 July 1970] 18645/71 Heading B2H Coal containing refuse is converted to a usable coal product having a predetermined maximum moisture content by (a) separating wet, refuse-containing coal into fractions according to particle size, including a finest fraction and at least one larger fraction; (b) removing refuse at least from said larger fraction; (c) dewatering said larger fraction to a moisture content below said predetermined moisture content; (d) mechanically dewatering said finest fraction in a continuous centrifuge of the screen bowl-type to provide a finest coal output of a moisture content above said predetermined maximum which when the said fractions are recombined, will provide a confined moisture content within said predetermined maximum; and (e) recombining the dewatered fractions to form the desired product. In one embodiment, Fig. 1, raw coal is screened at 12 into a first coarse fraction which is dewatered into an oscillating centrifuge dryer 14 and into a second fraction which passes with effluent from centrifuge 14 to a cleaner 18, e.g. concentrating table, cyclone or jig, which removes refuse particles. The cleaned coal fraction from 18 is screened at 20 into a medium fraction which is dewatered in an oxillating centrifuge dryer 24 or a thermal dryer and a finest fraction which passes to a froth flotation apparatus 30 for removal of further refuse particles. The cleaned coal slurry from 30 is dewatered in a continuous screen bowl centrifuge 34. The fractions from 14, 24 and 34 are delivered to a bin 16 where they are mixed to give the desired product. Instead of the froth flotation apparatus 30 a hydrocyclone may be used. Refuse from cleaner 18 is dewatered on a screen 40 and delivered to a container 42. Effluent from the downstream screen portion of centrifuge 34 is returned to flotation apparatus 30 while effluent from its upstream imperforate portion is directed with effluent from screen 40 and refuse from apparatus 30 to a thickener 48 of which the overflow may be recirculated, e.g. for initial wetting of coal, and the underflow is sent to a solid bowl centrifuge 50. The solids from the latter are discharged into container 42 whereas the effluent is recirculated to thickener 48.

A force to be measured is balanced by the force on a current-carrying conductor in a magnetic field, at least part of the current also being passed through a Hall plate in the same magnetic field so that the Hall voltage is indicative of the force to be measured. In Fig. 3, the pressure difference between chambers 2 and 4, which are separated by a diaphragm 3, provides the unknown force. Deflection of the diaphragm unbalances differential transformer 6, and the amplified output is applied in series to coil 7 and Hall plate 13. The central stem 9 of pot core 10 is magnetized by a coil 11 energized either from amplifier 15, or from a separate source. Stem 9 may alternatively be permanently magnetized, with coil 11 providing a control action or being omitted. The Hall voltage is measured by galvanometer 14 calibrated in suitable units.

Title: A process for the emulsion polymerisation of polymerisable substances
IPC: C08F2/22
Filed: 1947-07-16
Abstract: In a continuous emulsion polymerization process the monomer is emulsified in a non-acid reacting aqueous medium and the emulsion acidified, e.g. by addition of sulphuric, hydrochloric, nitric or acetic acid, preferably immediately before its introduction into the polymerization apparatus.  The necessity for stirring is thereby eliminated.  Catalysts, e.g. hydrogen peroxide and persulphates, may be added before, during or after emulsification. Specified monomers are vinyl chloride, vinylidene chloride, vinyl acetate, acrylic and methacrylic acid esters, acrylonitrile, styrene, fumaric acid esters and mixtures.  Additional monomer, e.g. in the form of similarly acidified emulsion, may be added at one or more points.  In the example, an aqueous emulsion of vinyl chloride was made in a turbo-mixer using sodium cetyl sulphate and shortly before introducing it into a tubular reaction vessel at 35 DEG  C., acid hydrogen peroxide solution was added to a pH value of 2.5.  Emulsion was continuously re-circulated by pumping from a point one-third from the beginning of the tube.
